Patented Feb. 10, 1931 PATENT ()FFICE CARL HEBSCHEL, OF BONN/RHINE, GERMANY COPYING ARRANGEMENT FOR COMMERCIAL BOOKS I Application filed February 14, 1929, Serial No.

' This invention relates to improvements in manifolding-devices, the principal object of the invention being to provide an im-' proved device of this character which is particularly well adapted for use in connection with sheets or cards contained in a file binder without removing them from the binder.

According to the present invention, a writing plate forming a fiat base for copying and adapted to receive the duplicate sheet is pivotally mounted on a framework which is connected to the cover of the book or to the file binder, preferably in a removable manner. In this fashion it is possible to utilize the simplicit of the copying process with all commerclal books and particularly with file binders. In the latter case there is the special advantage that removal of the individual, file sheets is eliminated and consequentl loss of the sheets is impossible. Considera le time is saved in copying and, moreover, the reliability of the book-keeping is substantially increased by the possibility of utilizin to thefull the advantages of the as file bin er.

One embodiment of the invention is illus trated by way of example in the accompanyingrdrawing in which:

igs. 1 and 2 area front elevation and plan respectivelyof a copying device embodying the present invention, combined with a file binder,

Fig. 3 is a section taken on the line AA of Fig. 2 to a larger scale and Fig. 4 is a section taken on the line B-B of Fig. 2 also to a larger scale. I The two parallel bars a of the frame for the .plane rigid base plate a are pivotally connected by means of a hinge pin 6 with 40. the bin es e attached to the cover (2 ofthe file bin er. The bars a of the frame when .laid on the table are held'in a horizontal or approximately horizontal position by two supporting legs 7.. Shoes g, upon which the plate a is pivoted so as I y the direction of the a ws D (Fig. 3), are adaptedto slide on the bars a. When the copyin device is to be employed, the base plate 0 lsswung into the opened file under the original sheet h'to be written; upon (Figs. 1

.and 2). At both longitudinal edges the plate 0 carries bars 2', between which and the plate 0 are formed spaces 71, wherein the duplicate sheet is is inserted at its edges and is thereby prevented from sliding out of place laterally. In order to bring the vertical rulings p of the duplicate sheet is into re ister with the corresponding rulings q o the original sheet h, the plate a may be dis laced at right x angles to the back Z of the file y rotating the butterfly key 1 which brings about displacement of the shoes 9 by means of the rack and pinion gear 8 and thus also causes displacement of the plate 0 in the direction of the arrows t to the left or right. The amount of the displacement is limited to the left by a stop pin 2 and to the right by a connecting bar 2'. After the rulings. go. have been adjusted the duplicate sheet k may be moved by hand in the spaces z" formed by the bars 6, parallel to the back Z of the file binder up or down in the direction of the arrows m until the lines n of the duplicate sheet 70 to be written upon are brought into register with the corresponding lines 0 of the original sheet h. After the duplicate sheet is has been adjusted precisely in the manner described relatively to the original sheet h, a carbon paper it or the like is laid between the two sheets h and 70 after which the copying can be performed. Upon the termination there-- i of the platec is swung out of the file and is brought, if desired, into the osition c (Fig.

1) ready to be swung bad again under another sheet of said file. So long as copies 35 are being made in' the file the plate 0 remains connected therewith so that the copying can be performed-very rapidly. If the copying arrangement is tp be used with another file then the hinge pin 6 is withdrawn to enable the frame to be removed and said frame is then combined in a corresponding fashion with the other file or the like with which it is to be employed.

It mayhappen possibly that the points of attachment-e for the frame are not located quite at rightrangles to the back Z andthus the plate 0 also does not ie in true parallelism with the original sheets h. In order to be able; if'nece ssary, to compensate for the (I bars a are made up of two separate bars a,

a". which are connected together by screws '0.

One bar a has a slot w in which the screws 42 of the other bar are adapted to be slid and set. In this way the overall length of the bar a, may be adjusted as desired enabling a slight angular adjustment of the plate 0 toobviate oblique positioning of the latter.

If the copying device is provided in the manner described only on one (the right hand) side of the file, then it is only possible to write upon the front sides of the original sheets 71.. If their rear sides 71. are to be written on after the leaves have been turned over, like the leaves of a book, then it is not possible to make copies since in this case the leaves do not come to lie on the plate 0. would only be possible then to obtain copies when writing upon the backs by removing the leaves kfrom the clips at of the securing means engaging perforations at the left hand edge 71;" of the leaves, turning the latter through 180 until the back lies uppermost and then re-inserting them with the same holes in the clips :0. In this case, however,

the written matter upon the front would be I upside down relatively to the written matter on the back owing to the turning of the leaf. To avoid this, according to the present invention, holes 51 are provided not only along the left hand edge h" but also along the right hand edge 72/ of the original sheet. If after the writing'up of the front It has been completed, the back h also is to be written upon, the original sheet is taken out of the clips .1; of the file and re-attached therein by means of the holes provided upon the right hand side b". In this manner the back becomes the front and the written matter is arranged in the correct manner upon both sides of the sheet. Consequently it is also possible to write upon the backs of the original sheets while it is only necessary to provide the copyof the file.
